material-layer-rows

Since next

a material asks for more than 3 layers (through a maskGraph) but HD draws only its first 3, because its graph has no shader slot (more than 16 distinct graphs) or the material table has no room for its rows; said once per material

Plain text
Severitywarning

Meaning

a material asks for more than 3 layers (through a maskGraph) but HD draws only its first 3, because its graph has no shader slot (more than 16 distinct graphs) or the material table has no room for its rows; said once per material

Fix

use fewer distinct graphs or fewer materials; the cost budget dropping layers at a low preset is not this warning
